In Technology Business Management taxonomy, how many layers support the structure?

• A. Four layers
• B. Three layers
• C. Five layers
• D. Two layers

Answer: (A)

Technology Business Management taxonomy uses a four-layer structure to connect business demand to IT delivery and finance. The top layer centers on business demand and outcomes, identifying the services the business needs. The next layer translates that demand into IT services—collections of capabilities, processes, people, and technology that deliver value. The third layer catalogs the technology components that realize those services—applications, platforms, data, and infrastructure. The bottom layer covers cost, funding, and financial management, tying every service and technology component to its cost and funding sources. This four-layer setup provides clear traceability from business goals through IT delivery to financial accountability, supporting better budgeting, optimization, and value realization. Fewer layers would blur important distinctions, while more layers could add unnecessary complexity.
